I ended up replacing that check with the concept of the graph.storage-version when I wrote the upgrade for 0.3.x. Either we can hard code 0.2.2 as allowed or we can back-port the upgrade functionality. 

It really comes down to how many more releases are we planning to have for 0.2.x.

I should be able to submit a fix for this Monday if no one else grabs it.

I was trying to do some testing:

JanusGraph 0.2.2 can not read graph from 0.2.1.

org.janusgraph.core.JanusGraphException: StorageBackend version is incompatible with current JanusGraph version: storage [0.2.1] vs. runtime [0.2.2]
